  • The sensor hubs are normally dispersed
  • Every one of these dissipated sensor hubs has the capacities to gather information and course information back to the sink and the end clients
  • Information are directed back to the end client by a multi-jump framework less design through the sink
  • The protocol stack consists of the application layer, transport layer, network layer, data link layer, physical layer, power management plane, mobility management plane, and task management plane
  • Different types of application software can be built and used on the application layer depending on the sensing tasks.

  • Vitality utilization is the most significant factor to decide the life of a sensor organize in light of the fact that normally sensor hubs are driven by battery.
  • Often energy efficiency in sensor networks is more difficult, as it requires not only reducing energy consumption but also prolonging the network's life as much as possible.
  • The streamlining should be possible by having vitality mindfulness in each part of structure and activity.

  • Security concerns in sensor networks are based on the need to know what we'll cover.
  • Data flows from several intermediate nodes in the sensor network, and the risk of data leakage is greater
  • The data received by the user should not be changed or altered as Data Integrity. Original data are altered by an attacker or due to harsh climate. The intruder can change the data as needed and send this new data to the receiver.

We hope the wide variety of areas of application can make sensor networks an important part of our future lives. Realization of sensor networks, however, needs to meet various constraints such as scalability, cost, hardware, topology change, environment and power consumption.]]> 2020-04-20 10:45:59 UTC https://padlet.com/fortniteacepack/dm31zwtvtxyfeihh/wish/517130754 Application cidhow3 https://padlet.com/fortniteacepack/dm31zwtvtxyfeihh/wish/517132232 Humidity

    • Temperature
    • Sound
    • Vibration
    • Pressure
    • Motion or
    • Pollutants 
    In order to cooperatively pass their data through the network to a main location or sink where the data can be observed and analysed.

A packet from each host is first sent to hub, and from there the hub sends the packet to its destination. The star topology is one of the most common computer network topologies.
    • The advantage of this type of network for wireless sensor networks includes simplicity, ability to keep the remote node’s power consumption to a minimum. It also allows low latency communications between the remote node and the base station.
    • The disadvantage of such a network is that the base station must be within radio transmission range of all the individual nodes and is not as robust as other networks due to its dependency on a single node to manage the network.

    • If an individual node fails, a remote node still can communicate to any other node in its range, which in turn, can forward the message to the desired location. In addition, the range of the network is not necessarily limited by the range in between single nodes; it can simply be extended by adding more nodes to the system.
    • The disadvantage of this type of network is in power consumption for the nodes that implement the multi-hop communications are generally higher than for the nodes that don’t have this capability, often limiting the battery life.
